ABSTRACT:
A baby stroller includes a pair of front legs, two handles and two rear legs pivotally coupled together, each of the supports has a member fixed on the upper end of the front leg and pivotally coupled to the lower end of the handle, a sleeve slidably engaged on the lower end of the handle, a knob pivotally secured to the lower end of the handle for engaging with the sleeve, and a protrusion extended from the member for engaging with the knob. The protrusion is retained in place by the knob when the sleeve is biased toward the knob and is disengaged from the knob when the knob is rotated such that the handle is rotatable relative to the front legs.
